Summary:
- Astronomers have identified a massive star, known as Betelgeuse, that is nearing the end of its life cycle and could explode as a supernova in the near future.
- Supernovas are the violent deaths of massive stars, releasing enormous amounts of energy and creating new elements that are essential for the formation of planets and life.
- The potential supernova of Betelgeuse would be visible from Earth and could provide valuable insights into the life cycle of stars and the formation of new elements in the universe.
